Abstract
BACKGROUND Food stores have gained attention as potential intervention targets for improving children's eating habits. There is a need for valid and reliable instruments to evaluate changes in food store snack and beverage availability secondary to intervention. The aim of this study was to develop a valid, reliable, and resource-efficient instrument to evaluate the healthfulness of food store environments faced by children. METHODS The SNACZ food store checklist was developed to assess availability of healthier alternatives to the energy-dense snacks and beverages commonly consumed by children. After pretesting, two trained observers independently assessed the availability of 48 snack and beverage items in 50 food stores located near elementary and middle schools in Portland, Oregon, over a 2-week period in summer 2012. Inter-rater reliability was calculated using the kappa statistic. RESULTS Overall, the instrument had mostly high inter-rater reliability. Seventy-three percent of items assessed had almost perfect or substantial reliability. Two items had moderate reliability (0.41-0.60), and no items had a reliability score less than 0.41. Eleven items occurred too infrequently to generate a kappa score. CONCLUSION The SNACZ food store checklist is a first-step toward developing a valid and reliable tool to evaluate the healthfulness of food store environments faced by children. The tool can be used to compare availability of healthier snack and beverage alternatives across communities and measure change secondary to intervention. As a wider variety of healthier snack and beverage alternatives become available in food stores, the checklist should be updated.

Abstract
BACKGROUND While there is a growing body of research on food environments for children, there has not been a published comprehensive review to date evaluating food environments outside the home and school and their relationship with diet in children. The purpose of this paper is to review evidence on the influence of the community and consumer nutrition environments on the diet of children under the age of 18 years. METHODS Our search strategy included a combination of both subject heading searching as well as natural language, free-text searching. We searched nine databases (MEDLINE, Web of Science, CINAHL, Embase, Scopus, ProQuest Public Health, PsycINFO, Sociological Abstracts, and GEOBASE) for papers published between 1995 and July 2013. Study designs were included if they were empirically-based, published scholarly research articles, were focused on children as the population of interest, fit within the previously mentioned date range, included at least one diet outcome, and exposures within the community nutrition environment (e.g., location and accessibility of food outlets), and consumer nutrition environment (e.g., price, promotion, and placement of food choices). RESULTS After applying exclusion and inclusion criteria, a total of 26 articles were included in our review. The vast majority of the studies were cross-sectional in design, except for two articles reporting on longitudinal studies. The food environment exposure(s) included aspects of the community nutrition environments, except for three that focused on the consumer nutrition environment. The community nutrition environment characterization most often used Geographic Information Systems to geolocate participants' homes (and/or schools) and then one or more types of food outlets in relation to these. The children included were all of school age. Twenty-two out of 26 studies showed at least one positive association between the food environment exposure and diet outcome. Four studies reported only null associations. CONCLUSIONS This review found moderate evidence of the relationship between the community and consumer nutrition environments and dietary intake in children up to 18 years of age. There is wide variation in measures used to characterize both the community and consumer nutrition environments and diet, and future research should work to decrease this heterogeneity.

A cross-sectional comparison of GIS-modelled and GPS-measured routes to school. Int J Health Geogr 2014; 13:5. [PMID: 24529075 PMCID: PMC3942764 DOI: 10.1186/1476-072x-13-5] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2013] [Accepted: 02/05/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The school journey may make an important contribution to children's physical activity and provide exposure to food and physical activity environments. Typically, Geographic Information Systems (GIS) have been used to model assumed routes to school in studies, but these may differ from those actually chosen. We aimed to identify the characteristics of children and their environments that make the modelled route more or less representative of that actually taken. We compared modelled GIS routes and actual Global Positioning Systems (GPS) measured routes in a free-living sample of children using varying travel modes. METHODS Participants were 175 13-14 yr old children taking part in the Sport, Physical activity and Eating behaviour: Environmental Determinants in Young people (SPEEDY) study who wore GPS units for up to 7 days. Actual routes to/from school were extracted from GPS data, and shortest routes between home and school along a road network were modelled in a GIS. Differences between them were assessed according to length, percentage overlap, and food outlet exposure using multilevel regression models. RESULTS GIS routes underestimated route length by 21.0% overall, ranging from 6.1% among walkers to 23.2% for bus users. Among pedestrians food outlet exposure was overestimated by GIS routes by 25.4%. Certain characteristics of children and their neighbourhoods that improved the concordance between GIS and GPS route length and overlap were identified. Living in a village raised the odds of increased differences in length (odds ratio (OR) 3.36 (1.32-8.58)), while attending a more urban school raised the odds of increased percentage overlap (OR 3.98 (1.49-10.63)). However none were found for food outlet exposure. Journeys home from school increased the difference between GIS and GPS routes in terms of food outlet exposure, and this measure showed considerable within-person variation. CONCLUSIONS GIS modelled routes between home and school were not truly representative of accurate GPS measured exposure to obesogenic environments, particularly for pedestrians. While route length may be fairly well described, especially for urban populations, those living close to school, and those travelling by foot, the additional expense of acquiring GPS data seems important when assessing exposure to route environments.

Abstract
This study evaluates the perceptions of teachers in charge of coordinating health education in schools: the School Health Coordinators (SHCs). It addresses the success and barriers of the development and implementation regarding the first year of healthy eating programmes in their schools. This research is based on 16 face-to-face semi-structured interviews with SHCs from Portuguese public schools offering from fifth to ninth grades. A thematic analysis was performed and themes were identified, taking into consideration similarities and differences among the participants' opinions. The results showed that the schools in this study often involved a set of separate healthy diet promotion activities with a low level of joint effort from all members of the school. Nevertheless, in Portugal, health education is based on the broad concept that school health promotion is compulsory for all schools. Two main barriers were identified in order to explain this divergence: structural and political idiosyncrasies among schools and the food environment inside and outside the schools. The results are discussed considering the wide range of factors influencing young people's eating behaviours and recommendations are made for the different agents interacting with them in order to promote appropriate eating habits.

Abstract
BACKGROUND Food environments may promote or undermine healthy behaviors, but questions remain regarding how individuals interact with their local food environments. PURPOSE This study incorporated an urban food environment audit as well as an examination of residents' food shopping behaviors within that context. METHODS In 2010, the research team audited the variety and healthfulness of foods available in 373 Philadelphia stores, using the validated Nutrition Environment Measures Survey in Stores (NEMS-S); higher scores indicate more diverse and healthful food inventories. The team also surveyed urban residents (n=514) regarding their food shopping. Descriptive and multivariate analyses (conducted in 2012) assessed variation in retail food environments and in shoppers' store choices. RESULTS Corner and convenience stores were common (78.6% of food retail outlets) and had the lowest mean NEMS-S scores of any store type. Most participants (94.5%) did their primary food shopping at higher-scoring chain supermarkets, and the majority of participants did not shop at the supermarket closest to home. Supermarket offerings varied, with significantly fewer healthful foods at supermarkets closest to the homes of disadvantaged residents. In multivariate analyses, participants were significantly more likely to shop at supermarkets closest to home if those supermarkets had higher NEMS-S scores. CONCLUSIONS These data suggest that, when possible, shoppers chose supermarkets that offered more variety and more healthful foods. Findings from this study also reinforce concern regarding unhealthy immediate food environments for disadvantaged residents, who disproportionately relied on nearby stores with more limited food items. Interventions to improve nutrition and health should address not only food store proximity but also diversity of healthful foods available.

Abstract
OBJECTIVE To develop a reliable food store observational data collection instrument to be used for measuring product availability, pricing, and promotion. DESIGN Observational data collection. SETTING A total of 120 food stores (26 supermarkets, 34 grocery stores, 54 gas/convenience stores, and 6 mass merchandise stores) in the Chicago metropolitan statistical area. MAIN OUTCOME MEASURES Inter-rater reliability for product availability, pricing, and promotion measures on a food store observational data collection instrument. ANALYSIS Cohen's kappa coefficient and proportion of overall agreement for dichotomous variables and intra-class correlation coefficient for continuous variables. RESULTS Inter-rater reliability, as measured by average kappa coefficient, was 0.84 for food and beverage product availability measures, 0.80 for interior store characteristics, and 0.70 for exterior store characteristics. For continuous measures, average intra-class correlation coefficient was 0.82 for product pricing measures; 0.90 for counts of fresh, frozen, and canned fruit and vegetable options; and 0.85 for counts of advertisements on the store exterior and property. CONCLUSIONS AND IMPLICATIONS The vast majority of measures demonstrated substantial or almost perfect agreement. Although some items may require revision, results suggest that the instrument may be used to reliably measure the food store environment.

Abstract
Obesity prevalence among US children and adolescents has tripled in the past three decades. Consequently, dramatic increases in chronic disease incidence are expected, particularly among populations already experiencing health disparities. Recent evidence identifies characteristics of "obesogenic" neighborhood environments that affect weight and weight-related behaviors. This study aimed to examine associations between built, socioeconomic, and social characteristics of a child's residential environment on body mass index (BMI), diet, and physical activity. We focused on pre-adolescent children living in New Haven, Connecticut to better understand neighborhood environments' contribution to persistent health disparities. Participants were 1048 fifth and sixth grade students who completed school-based health surveys and physical measures in fall 2009. Student data were linked to US Census, parks, retailer, and crime data. Analyses were conducted using multilevel modeling. Property crimes and living further from a grocery store were associated with higher BMI. Students living within a 5-min walk of a fast food outlet had higher BMI, and those living in a tract with higher density of fast food outlets reported less frequent healthy eating and more frequent unhealthy eating. Students' reported perceptions of access to parks, playgrounds, and gyms were associated with more frequent healthy eating and exercise. Students living in more affluent neighborhoods reported more frequent healthy eating, less unhealthy eating, and less screen time. Neighborhood social ties were positively associated with frequency of exercise. In conclusion, distinct domains of neighborhood environment characteristics were independently related to children's BMI and health behaviors. Findings link healthy behaviors with built, social, and socioeconomic environment assets (access to parks, social ties, affluence), and unhealthy behaviors with built environment inhibitors (access to fast food outlets), suggesting neighborhood environments are an important level at which to intervene to prevent childhood obesity and its adverse consequences.

Abstract
Many small grocery stores or "bodegas" sell prepared or ready-to-eat items, filling a niche in the food environment similar to fast-food restaurants. However, little comparative information is available about the nutrition environments of bodegas and fast-food outlets. This study compared the nutrition environments of bodegas and national chain fast-food restaurants using a common audit instrument, the Nutrition Environment Measures Study in Restaurants (NEMS-R) protocol. The analytic sample included 109 bodegas and 107 fast-food restaurants located in New York City neighborhoods in the upper third and lower third of the census tract poverty rate distribution. Inter-rater reliability was evaluated in 102 food outlets, including 31 from the analytic sample and 71 from a supplementary convenience sample. The analysis compared scores on individual NEMS-R items, a total summary score, and subscores indicating healthy food availability, nutrition information, promotions of healthy or unhealthy eating, and price incentives for healthy eating, using t tests and χ(2) statistics to evaluate differences by outlet type and neighborhood poverty. Fast-food restaurants were more likely to provide nutrition information, and bodegas scored higher on healthy food availability, promotions, and pricing. Bodegas and fast-food restaurants had similar NEMS-R total scores (bodegas 13.09, fast food 14.31; P=0.22). NEMS-R total scores were higher (indicating healthier environments) in low- than high-poverty neighborhoods among both bodegas (14.79 vs 11.54; P=0.01) and fast-food restaurants (16.27 vs 11.60; P<0.01). Results imply different policy measures to improve nutrition environments in the two types of food outlets.

Abstract
This study examined food availability along children's paths to and from elementary school, and associations with change in body mass index (BMI) and waist circumference over 1 year. Secondary data from 319 children aged 8-13 years from the "Multiple Opportunities to Reach Excellence" Project was used. Child anthropometry and demographic variables were obtained at baseline (2007) and 1 year follow-up. Food outlet locations (n = 1,410) were obtained from the Baltimore City Health Department and validated by ground-truthing. Secondary data on healthy food availability within select food stores in Baltimore City in 2007 were obtained via a validated food environment assessment measure, the Nutrition Environments Measures Study. Multilevel models were used to examine associations between availability of healthy food and number of various food outlets along paths to school and child anthropometric change over 1 year. Controlling for individual-, neighborhood-, and school-level characteristics, results indicated that higher healthy food availability within a 100 m buffer of paths to school was associated with 0.15 kg/m(2) lower BMI gain (p = 0.015) and 0.47 cm smaller waist circumference gain (p = 0.037) over 1 year. Although prior research has illuminated the importance of healthy food choices within school and home environments, the current study suggests that exposure to the food environment along paths to school should be further explored in relation to child health outcomes.

Abstract
Background The inclusion of toys in food packages is a common marketing practice, and it is suspected of promoting obesogenic behaviours. This study aimed to determine whether toys packaged with food are indeed increasing the amount of food eaten by children, and if this effect is enhanced by contemporary exposure to TV and/or advertising. Methods A total of 600 children (balanced according to gender and age groups, 3–6 and 7–10 years old) were randomized in three school facilities in Argentina, Brazil and Mexico and exposed to food (snacks) alone or food associated with toys in an experimental setting. All of the children received the same meal at lunchtime. The products were packages in which chocolate was associated with toys in an egg-shaped container partially filled by chocolate. The children were asked to eat ad libitum for 20 minutes during the afternoon break. In addition, the children were randomized into two groups and either shown or not shown a movie cartoon, with three different levels of exposure to commercials in the TV viewing condition (1, 2 or 3 advertisements). Results No significant differences emerged between the “toys” and “no toys” groups even after taking into account exposure to TV, commercials and other confounding factors. Conclusions The inclusion of toys in food packages was not shown per se to lead to an increase in the caloric intake of children.

Abstract
Given the growing contribution of snacks to dietary intake and the need for effective strategies to reduce obesity, it is important to consider whether snacking behaviors contribute to high BMI in childhood. This review summarizes US research that has addressed trends in snacking behavior and its contribution to dietary intake, as well as research describing snack food availability in settings where youth spend their time. In addition, it comprehensively reviews studies conducted in the United States and internationally that have examined associations of snacking behavior with weight. Research published between January, 2000, and December, 2011, was identified by searching PubMed and MEDLINE databases, and by examining bibliographies of relevant studies. Recent analyses of trends in dietary intake have shown there were significant increases in the contribution of energy-dense, nutrient-poor foods to snacking kilocalories over the past few decades. Although snacks can contribute to intake of key nutrients, frequent snacking has been associated with higher intake of total energy and energy from added and total sugars. Assessments in schools and retail stores have further indicated that energy-dense, nutrient-poor snacks are widely available in settings where youth spend their time. The majority of studies either found no evidence of a relationship between snacking behavior and weight status or found evidence indicating that young people who consumed more snacks were less likely to be obese; however, additional research is needed to address various methodological limitations. Recommendations for future research are provided to address knowledge gaps and inform the development of interventions.

Abstract
The purpose of this study was to use the theory of planned behavior to explain two types of snack food consumption among boys and girls (girls n = 98; boys n = 69), which may have implications for future theory-based health promotion interventions. Between genders, there was a significant difference for calorie-dense/nutrient-poor snacks ( p = .002), but no difference for fruit and vegetable snacks. Using stepwise multiple regression, attitudes, perceived behavioral control, and subjective norms accounted for a large amount of the variance of intentions (girls = 43.3%; boys = 55.9%); however, for girls, subjective norms accounted for the most variance, whereas for boys, attitudes accounted for the most variance. Calories from calorie-dense/nutrient-poor snacks and fruit and vegetable snacks were also predicted by intentions. For boys, intentions predicted 6.4% of the variance for fruit and vegetable snacks ( p = .03) but was not significant for calorie-dense/nutrient-poor snacks, whereas for girls, intentions predicted 6.0% of the variance for fruit and vegetable snacks ( p = .007), and 7.2% of the variance for calorie-dense/nutrient-poor snacks ( p = .004). Results suggest that the theory of planned behavior is a useful framework for predicting snack foods among children; however, there are important differences between genders that should be considered in future health promotion interventions.

Abstract
The HEALTHY trial was designed to take a primary prevention approach to risk factors for type 2 diabetes in youth, primarily obesity. The study involved over 6,000 students at 42 middle schools across the U.S. Half received an integrated intervention program of components addressing the school food environment, physical education, lifestyle behaviors, and promotional messaging. The intervention was designed to be more comprehensive than previous efforts, and the research was amply funded. Although the primary objective of reducing the percentage of overweight and obesity in schools that received the intervention program, as compared with control schools, was not obtained, key secondary outcomes indicated an intervention effect. In retrospect, senior investigators involved in the study's design, conduct, and analysis discuss weaknesses and strengths and offer recommendations for future research efforts that address prevention of childhood obesity from a public health perspective.

Abstract
BACKGROUND Literature on food environments is expanding rapidly, yet a gap exists regarding the role of the U.S. Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on healthy food availability. In October 2009, the U.S. Department of Agriculture revised the WIC food package, requiring certified stores to stock fresh produce, whole grains, and lower-fat milk. PURPOSE The goal of this study is to compare availability of foods in stores that are versus those that are not WIC-certified before and after the policy change. METHODS Store inventories were collected in 45 corner stores in Hartford CT with four inventories each (180 total inventories) from January 2009 to January 2010. Data on availability and variety of fresh fruits, fresh vegetables, whole grains, and lower-fat milk were recorded. Analyses were completed in 2012 using Fisher's exact test, chi-square, and t-tests for descriptive analyses and multilevel models to measure food availability longitudinally (significance at p<0.05). RESULTS Controlling for covariates, WIC-certified vendors carried more varieties of fresh fruit (p<0.01); a greater proportion of lower-fat milk (p<0.01); and had greater availability of whole grain bread (p<0.01) and brown rice (p<0.05) than vendors without WIC authorization after the policy change. Conversely, for all outcomes, stores without WIC authorization did not significantly increase healthy food availability. CONCLUSIONS The 2009 WIC revisions increased availability of healthy foods among WIC-certified vendors compared to those without WIC authorization in Hartford CT. For many residents without a car, these changes can create a convenient shopping location for healthy foods when a larger supermarket is not nearby.

Abstract
BACKGROUND Product assortment (presence and variety) is a key in-store marketing strategy to influence consumer choice. Quantifying the product assortment of healthier and less-healthy foods and beverages in convenience stores can inform changes in the food environment. PURPOSE To document product assortment (i.e., presence and variety of specific foods and beverages) in convenience stores. METHODS Observational survey data were collected onsite in 2011 by trained promotora-researchers in 192 convenience stores. Frequencies of presence and distributions of variety were calculated in 2012. Paired differences were examined using the Wilcoxon matched-pairs signed-rank test. RESULTS Convenience stores displayed a large product assortment of sugar-sweetened beverages (median 86.5 unique varieties); candy (76 varieties); salty snacks (77 varieties); fried chips (44 varieties); cookies and pastries (19 varieties); and frozen sweets (21 varieties). This compared with 17 varieties of non-sugar sweetened beverages and three varieties of baked chips. The Wilcoxon signed-rank test confirmed a (p<0.001) greater variety of sugar-sweetened than non-sugar-sweetened beverages, and of fried chips compared with baked chips. Basic food items provided by convenience stores included milk (84% of stores); fresh fruit (33%); fresh vegetables (35%); canned vegetables (78%); white bread (71%); and deli-style packaged meat (57%). Healthier versions of milk, canned fruit, canned tuna, bread, and deli-style packaged meat were displayed in 17%-71% of convenience stores. CONCLUSIONS Convenience stores in this area provide a greater assortment of less-healthy compared with healthier foods and beverages. There are opportunities to influence consumer food choice through programs that alter the balance between healthier and less-healthy foods and beverages in existing convenience stores that serve rural and underserved neighborhoods and communities.

Abstract
OBJECTIVES We assessed the effectiveness of an initiative to increase the stock and promotion of healthy foods in 55 corner stores in underserved neighborhoods. METHODS We evaluated the intervention through in-store observations and preintervention and postintervention surveys of all 55 store owners as well as surveys with customers at a subset of stores. RESULTS We observed an average of 4 changes on a 15-point criteria scale. The most common were placing refrigerated water at eye level, stocking canned fruit with no sugar added, offering a healthy sandwich, and identifying healthier items. Forty-six (84%) store owners completed both surveys. Owners reported increased sales of healthier items, but identified barriers including consumer demand and lack of space and refrigeration. The percentage of customers surveyed who purchased items for which we promoted a healthier option (low-sodium canned goods, low-fat milk, whole-grain bread, healthier snacks and sandwiches) increased from 5% to 16%. CONCLUSIONS Corner stores are important vehicles for access to healthy foods. The approach described here achieved improvements in participating corner stores and in some consumer purchases and may be a useful model for other locales.

Abstract
Increase in the consumption of food and drinks outside the home by adolescents and young people and associations with rising levels of obesity is a significant concern worldwide and it has been suggested that the food environment around schools may be a contributory factor. As few studies have explored this issue in a UK setting, we examined whether different types of food outlets are clustered around public secondary schools in Glasgow, and whether this pattern differed by social disadvantage. We found evidence of clustering of food outlets around schools but a more complex picture in relation to deprivation was observed. Across all schools there were numerous opportunities for pupils to purchase energy dense foods locally and the implications for policy are discussed.

Abstract
The aim of this study was to examine the association between the local food environment and obesity proportions among 3- to 4-year-old children who were participants in the WIC program in Los Angeles County using spatial analyses techniques. ArcGIS, spatial analysis software, was used to compute the retail food environment index (RFEI) per ZIP code. GeoDa, spatial statistics software was employed to check for spatial autocorrelation and to control for permeability of the boundaries. Linear regression and ANOVA were used to examine the impact of the food environment on childhood obesity. Fast-food restaurants represented 30% and convenience stores represented 40% of the sum of food outlets in areas where WIC participants reside. Although there was no statistically significant association between RFEI and 3- to 4-year-old obesity proportions among WIC children, analysis of variance (ANOVA) tests demonstrated statistically significant positive associations between obesity and the number of convenience stores and the number of supermarkets. Our findings suggest that RFEI, as currently constructed, may not be the optimal way to capture the food environment. This study suggests that convenience stores and supermarkets are a likely source of excess calories for children in low-income households. Given the ubiquity of convenience stores in low-income neighborhoods, interventions to improve availability of healthy food in these stores should be part of the many approaches to addressing childhood obesity. This study adds to the literature by examining the validity of the RFEI and by demonstrating the need and illustrating the use of spatial analyses, using GeoDA, in the environment/obesity studies.

Abstract
This study examined the extent to which constructs of the theory of planned behavior (TPB) can predict the consumption of two types of snack foods among elementary school children. A 15-item instrument tested for validity and reliability measuring TPB constructs was developed and administered to 167 children. Snack foods were evaluated using a modified 24-hour recall method. On average, children consumed 302 calories from snack foods per day. Stepwise multiple regression found that attitudes, subjective norms, and perceived control accounted for 44.7% of the variance for intentions. Concurrently, intentions accounted for 11.3% of the variance for caloricallydense snack food consumption and 8.9% of the variance for fruit and vegetable snack consumption. Results suggest that the theory of planned behavior is an efficacious theory for these two behaviors. Future interventions should consider using this theoretical framework and aim to enhance children's attitudes, perceived control, and subjective norms towards snack food consumption.

Abstract
BACKGROUND Built environment features of neighborhoods may be related to obesity among adolescents and potentially related to obesity-related health disparities. The purpose of this study was to investigate spatial relationships between various built environment features and body mass index (BMI) z-score among adolescents, and to investigate if race/ethnicity modifies these relationships. A secondary objective was to evaluate the sensitivity of findings to the spatial scale of analysis (i.e. 400- and 800-meter street network buffers). METHODS Data come from the 2008 Boston Youth Survey, a school-based sample of public high school students in Boston, MA. Analyses include data collected from students who had georeferenced residential information and complete and valid data to compute BMI z-score (n = 1,034). We built a spatial database using GIS with various features related to access to walking destinations and to community design. Spatial autocorrelation in key study variables was calculated with the Global Moran's I statistic. We fit conventional ordinary least squares (OLS) regression and spatial simultaneous autoregressive error models that control for the spatial autocorrelation in the data as appropriate. Models were conducted using the total sample of adolescents as well as including an interaction term for race/ethnicity, adjusting for several potential individual- and neighborhood-level confounders and clustering of students within schools. RESULTS We found significant positive spatial autocorrelation in the built environment features examined (Global Moran's I most ≥ 0.60; all p = 0.001) but not in BMI z-score (Global Moran's I = 0.07, p = 0.28). Because we found significant spatial autocorrelation in our OLS regression residuals, we fit spatial autoregressive models. Most built environment features were not associated with BMI z-score. Density of bus stops was associated with a higher BMI z-score among Whites (Coefficient: 0.029, p < 0.05). The interaction term for Asians in the association between retail destinations and BMI z-score was statistically significant and indicated an inverse association. Sidewalk completeness was significantly associated with a higher BMI z-score for the total sample (Coefficient: 0.010, p < 0.05). These significant associations were found for the 800-meter buffer. CONCLUSION Some relationships between the built environment and adolescent BMI z-score were in the unexpected direction. Our findings overall suggest that the built environment does not explain a large proportion of the variation in adolescent BMI z-score or racial disparities in adolescent obesity. However, there are some differences by race/ethnicity that require further research among adolescents.

Abstract
This study examined the relationship between the neighborhood food environment and the food purchasing behaviors among adolescents. Grade 7 and 8 students (n = 810) at 21 elementary schools in London, Ontario, Canada completed a questionnaire assessing their food purchasing behaviors. Parents of participants also completed a brief questionnaire providing residential address and demographic information. A Geographic Information System (GIS) was used to assess students' home and school neighborhood food environment and land use characteristics. Logistic regression analysis was conducted to assess the influence of the home neighborhood food environment on students' food purchasing behaviors, while two-level Hierarchical Non-Linear Regression Models were used to examine the effects of school neighborhood food environment factors on students' food purchasing behaviors. The study showed that approximately 65% of participants reported self-purchasing foods from fast-food outlets or convenience stores. Close proximity (i.e., less than 1 km) to the nearest fast-food outlet or convenience store in the home neighborhood increased the likelihood of food purchasing from these food establishments at least once per week by adolescents (p < 0.05). High fast-food outlet density in both home and school neighborhoods was associated with increased fast-food purchasing by adolescents (i.e., at least once per week; p < 0.05). In conclusion, macro-level regulations and policies are required to amend the health-detracting neighborhood food environment surrounding children and youth's home and school.

Abstract
OBJECTIVE To explore the barriers associated with the adoption of the Alberta Nutrition Guidelines for Children and Youth in schools according to characteristics of the innovation (guidelines) and the organization (schools). DESIGN Cross-sectional telephone survey. SETTING AND PARTICIPANTS Schools in Alberta, Canada. Principals from 357 schools. MAIN OUTCOME MEASURE Barriers to adopting the nutrition guidelines. ANALYSIS A 19-question telephone survey, including open- and closed-ended questions, was used to obtain information regarding schools' characteristics and barriers to adopting the guidelines. Qualitative data were coded according to common themes a priori, based on constructs from the Diffusion of Innovations framework. RESULTS Schools reported many barriers related to the relative advantage, compatibility, and complexity of adopting the guidelines. Parents' resistance to change and cost were the key reported barriers. Lack of knowledge, student preferences, the physical location of the school, and barriers related to the provision of healthful food were also reported. CONCLUSIONS AND IMPLICATIONS Disseminating guidelines without providing adequate support for their implementation may not promote change within the school setting. School nutrition initiatives need to involve the parents and have access to sufficient financial and human resource support.

Abstract
PURPOSE. To identify environmental barriers and facilitators of children's physical activity and healthy eating in a rural county. DESIGN. Community-based participatory research using mixed methods, primarily qualitative. SETTING. A rural Oregon county. SUBJECTS. Ninety-five adults, 6 high school students, and 41 fifth-grade students. MEASURES. In-depth interviews, focus groups, Photovoice, and structured observations using the Physical Activity Resource Assessment, System for Observing Play and Leisure Activity, Community Food Security Assessment Toolkit, and School Food and Beverage Marketing Assessment Tool. ANALYSIS. Qualitative data were coded by investigators; observational data were analyzed using descriptive statistics. The findings were triangulated to produce a composite of environmental barriers and assets. RESULTS. Limited recreational resources, street-related hazards, fear of strangers, inadequate physical education, and denial of recess hindered physical activity, whereas popularity of youth sports and proximity to natural areas promoted physical activity. Limited availability and high cost of healthy food, busy lifestyles, convenience stores near schools, few healthy meal choices at school, children's being permitted to bring snacks to school, candy used as incentives, and teachers' modeling unhealthy eating habits hindered healthy eating, whereas the agricultural setting and popularity of gardening promoted healthy eating. CONCLUSIONS. This study provides data on a neglected area of research, namely environmental determinants of rural childhood obesity, and points to the need for multifaceted and multilevel environmental change interventions.

Abstract
Background Intermittent monitoring of food intake at the population level is essential for the planning and evaluation of national dietary intervention programs. Social-economic changes in Lithuania have likely affected dietary habits, but only a limited number of temporal studies on food intake trends among young population groups have been published. The aim of this study was to investigate changes in eating habits among Lithuanian school-aged children from 2002 to 2010, and to explore the association of these changes with the respondents' reported socio-economic status (SES). Methods We used Lithuanian data from the cross-national Health Behaviour in School-aged Children (HBSC) study collected in 2002, 2006 and 2010. Analyses were conducted on comparable questionnaire-based data from children aged 11, 13 and 15 (total n = 17,189) from a random sample of schools. A food frequency questionnaire was used to investigate frequencies of food consumption. Logistic regression was used to examine the affects of changing social variables on reported diet trends. Results In Lithuania, school-aged children have low intakes of fruits and vegetables. Only 21.1% of boys and 27.1% of girls reported daily fruit consumption. Similarly, 24.9% of boys and 29.6% of girls disclosed vegetable intake at least once daily. Comparing 2010 to 2002, the proportion of girls who consumed fruits daily increased from 24.2% to 31.0% (p < 0.001) but the proportion of boys who consumed vegetables daily decreased from 29.3% to 23.1% (p < 0.001). In 2006, for both sexes, there were observed increases in regular (at least five days a week) intake of sweets and chocolates, biscuits and pastries, and soft drinks; however, in the next survey (2010) these figures decreased. In addition, between 2006 and 2010, a substantial decrease in regular consumption of chips and fast food was also detected. Fruit and vegetable consumption as well as intake of sweets and chocolates, biscuits and pastries and soft drinks increased with family social-economic status and family material wealth. Trends in consumption of fruits, and other foods, and their association with changing social variables were demonstrated using the ORs estimated by three logistic models, using 2002 as the reference point. Changes in social variables from 2002 to 2010 affected the likelihood of daily consumption of fruits among boys by 22.5% (the corresponding OR decreased from 1.11 to 0.86) and among girls by 34.0% (the corresponding OR decreased from 1.41 to 1.12). Over the study period, changing social variables had little impact on the daily consumption of vegetables and other foods. Conclusions Based on the food consumption trends observed in Lithuania, increases in consumption of fruits and vegetables should be promoted, along with a reduction in the intake of less healthy choices, such as soft drinks and high-fat, high-sugar snack foods, by diminishing social inequalities in food consumption.

Abstract
OBJECTIVE Literature on food environments has expanded rapidly, yet most research focuses on stores and community characteristics without integrating customer-level data. The present study combines customer shopping behaviour with store food inventory data. DESIGN Face-to-face interviews were conducted with customers shopping in corner stores to measure food shopping behaviour, household food security and demographics. Store inventories were conducted to measure availability of healthy food in corner stores. Multilevel logistic regression models estimated the probability of customers purchasing a food item given the availability of that item in the store. SETTING Nineteen corner stores in Hartford, CT, USA, average size 669 ft(2) (62.15 m(2)). SUBJECTS Sample of 372 customers. RESULTS The majority of customers were Black or Hispanic (54 % and 40 %, respectively) and 61 % experienced food insecurity. For each additional type of fruits or vegetables available in the store, the estimated odds of a customer purchasing fruits increased by 12 % (P = 0.03) and the odds for purchasing vegetables increased by 15 % (P = 0.01). Customers receiving the Supplemental Nutrition Assistance Program (SNAP) were 1.7 times as likely to purchase fruit as those not receiving SNAP (P = 0.04). Greater availability of reduced-fat milk was not associated with increased likelihood of customers purchasing reduced-fat milk. CONCLUSIONS There is a positive association between fruit and vegetable variety and the probability that a customer purchases fruits and vegetables. Increasing the selection of produce in corner stores may increase their consumption by food-insecure and low-income residents at risk for health disparities. These findings have implications for future store interventions and food policies.

Abstract
OBJECTIVE Many recent policies focus on socioeconomic inequities in availability of healthy food stores and restaurants. Yet understanding of how socioeconomic inequities vary across neighbourhood racial composition and across the range from rural to urban settings is limited, largely due to lack of large, geographically and socio-demographically diverse study populations. Using a national sample, the authors examined differences in neighbourhood food resource availability according to neighbourhood-level poverty and racial/ethnic population in non-urban, low-density urban and high-density urban areas. DESIGN Cross-sectional data from an observational cohort study representative of the US middle and high school-aged population in 1994 followed into young adulthood. PARTICIPANTS Using neighbourhood characteristics of participants in the National Longitudinal Study of Adolescent Health (Wave III, 2001-2002; n=13 995 young adults aged 18-28 years representing 7588 US block groups), the authors examined associations between neighbourhood poverty and race/ethnicity with neighbourhood food resource availability in urbanicity-stratified multivariable linear regression. PRIMARY AND SECONDARY OUTCOME MEASURES Neighbourhood availability of grocery/supermarkets, convenience stores and fast-food restaurants (measured as number of outlets per 100 km roadway). RESULTS Neighbourhood race and income disparities were most pronounced in low-density urban areas, where high-poverty/high-minority areas had lower availability of grocery/supermarkets (β coefficient (β)=-1.91, 95% CI -2.73 to -1.09) and convenience stores (β=-2.38, 95% CI -3.62 to -1.14) and greater availability of fast-food restaurants (β=4.87, 95% CI 2.26 to 7.48) than low-poverty/low-minority areas. However, in high-density urban areas, high-poverty/low-minority neighbourhoods had comparatively greater availability of grocery/supermarkets (β=8.05, 95% CI 2.52 to 13.57), convenience stores (β=2.89, 95% CI 0.64 to 5.14) and fast-food restaurants (β=4.03, 95% CI 1.97 to 6.09), relative to low-poverty/low-minority areas. CONCLUSIONS In addition to targeting disproportionate fast-food availability in disadvantaged dense urban areas, our findings suggest that policies should also target disparities in grocery/supermarket and fast-food restaurant availability in low-density areas.

Abstract
The aim of this study is to present the development of the Meanings of Eating Index (MEI) in a diverse sample of children. Exploratory factor analysis was performed on MEI items. Factors with eigenvalues above 1.0 were retained. Items that loaded on multiple factors or with item-total correlations below 0.50 were discarded. A 24-item, 5-factor scale comprised the final MEI. Personal Negative Emotions and Disturbed Eating were positively associated with frequency of high calorie snack food intake (r=0.21, p<0.05; r=0.33, p<0.01), and Personal Well Being was positively associated with eating vegetables more frequently (r=0.20; p<0.05). Eating on Behalf of Others was negatively associated with frequency of vegetable intake (r=-.20; p<0.05). Pleasure Eating was not associated with dietary intake. The MEI shows promise as a tool for understanding the affective determinants of dietary intake in minority youth.

Abstract
The study's objectives were to gain school personnel's (1) perceptions on diet, physical activity, body size, and obesity, (2) description of school food and physical activity practices, and (3) recommendations for programs to prevent adolescent obesity. The study took place in six junior secondary schools of varying socioeconomic status in Gaborone, Botswana. Using a qualitative descriptive design, semistructured interviews were conducted with key school personnel. Directed content analysis was used to summarize the findings. School personnel believed that obesity was an important problem. They felt that school food was unhealthy and that physical activity was provided insufficiently. Participants shared enthusiasm for a school-based health-promoting intervention that must be fun and include active engagement and education on healthy lifestyles for all students. Participants supported on-site food shop inventory changes and physical activity programs. Potential barriers listed were schools' financial resources, interest of students, and time limitations of all involved.

Abstract
CONTEXT The IOM released an expert committee report in 2005 that assessed the nature, extent, and influence of food and beverage marketing practices on the diets and health of American children and adolescents. The report concluded that prevailing marketing practices did not support a healthful diet and offered recommendations for diverse stakeholders to promote a healthful diet. The investigators evaluated progress made by food, beverage, and restaurant companies; trade associations; entertainment companies; and the media to achieve the IOM report recommendations over 5 years. EVIDENCE ACQUISITION A literature review was conducted of electronic databases and relevant government, industry, and media websites between December 1, 2005, and January 31, 2011. Evidence selection was guided by the IOM LEAD principles (i.e., locate, evaluate, and assemble evidence to inform decisions) and five qualitative-research criteria, and it was validated by data and investigator triangulation. The investigators selected and categorized 117 data sources into two evidence tables used to evaluate industry progress (i.e., no, limited, moderate, and extensive). EVIDENCE SYNTHESIS Food and beverage companies made moderate progress; however, limited progress was made by other industry subsectors. Industry stakeholders used integrated marketing communications (IMC) to promote primarily unhealthy products, which threaten children's and adolescents' health and miss opportunities to promote a healthy eating environment. CONCLUSIONS Diverse industry stakeholders have several untapped opportunities to advance progress by promoting IMC to support a healthful diet; substantially strengthening self-regulatory programs; supporting truthful and non-misleading product labeling and health claims; engaging in partnerships; and funding independent evaluations of collective efforts.

Abstract
There is growing evidence that exposure to food marketing influences dietary preferences among youth. Few studies exploring this association, however, have focused on the retail food store environment where families negotiate the influence of food and beverage marketing on purchasing practices. Consequently, we sought to examine: (i) the extent to which foods marketed on the internet and television to youth are also available and marketed in retail food stores, and (ii) whether differences exist in the marketing practices across store types and by neighborhood racial composition. In 2008, a cross-sectional survey of 118 food stores was conducted in four Midwestern cities in the United States. Results showed that 82% of stores assessed carried items commonly marketed to youth via television or the internet. The items most likely to have some type of marketing technique were noncarbonated drinks (97.7%), fruit and cereal bars (76.9%), and soda (62.2%). Grocery stores were significantly more likely than convenience stores to have marketing for breads and pastries (34.6% vs. 17.9%), breakfast cereals (52.0% vs. 22.9%), cookies and crackers (54.2% vs. 25.3%), dairy (70.8% vs. 42.7%), and ice cream (23.8% vs. 9.8%). Stores located in black neighborhoods were significantly more likely to have marketing, in comparison to white neighborhoods, for breads and pastries (35.7% vs. 17.1%), breakfast cereals (44.4% vs. 25.0%), and cookies and crackers (48.1% vs. 26.3%). Our results highlight the importance of examining food marketing techniques in the retail food store environment, where visual cues from television and the internet may be reinforced.

Abstract
OBJECTIVE To assess the relationship between adolescent perception of time to walk to neighbourhood food retail outlets and purchasing of sugar-sweetened beverages (SSB), fast and convenience food items, and to test for differences by urban v. suburban environment. DESIGN Cross-sectional observational study. SETTING Twin Cities Metropolitan Area, Minnesota, USA. SUBJECTS Adolescents from two studies completed survey-based measures on perceptions of time to walk to food retail outlets from home, purchasing patterns of SSB and fast and convenience store items, perceptions of personal safety and pedestrian infrastructure, and demographic characteristics. Descriptive analysis, Spearman correlations and multivariate linear regression, accounting for clustering, were conducted. RESULTS There were 634 adolescents, approximately half male, predominantly white, with a middle-class background. Greater perceived time to food outlets was associated with less frequent purchasing of SSB, convenience store foods and fast-food items. Multivariate models showed that a perceived shorter walking time (i.e. 1-5 v. 31+ min) was significantly associated with more SSB purchasing. SSB purchases were also significantly associated with the number of food outlets within a 10 min walk (B = 0·05, P = 0·02). CONCLUSIONS A reduction in consumption of SSB and other energy-dense snacks is an important obesity prevention approach. An approach offering alternatives or reducing exposure in addition to education to alter purchasing habits may contribute to improving dietary habits and reducing the obesity epidemic.

Abstract
Adolescent obesity is a national public health problem, particularly among urban populations. Recent evidence has linked neighborhood food environments to health and nutrition status, with easier access to convenience stores being associated with increased risk for obesity. Little is known about the availability of healthy purchasing options within small, urban food stores, or the extent to which these factors are relevant to youth. The objective of this research was to characterize various features of the food environment within small convenience stores located nearby urban junior high and high schools. In-store audits were conducted in 63 stores located within 800 m of 36 urban Minnesota public secondary schools. Results indicated that a limited number of healthier beverages (i.e., water and 100% fruit juice) and snack options (i.e., nuts and pretzels) were available at most stores (≥85%). However, a wide range of healthy snack options were typically not available, with many specific items stocked in less than half of stores (e.g., low-fat yogurt in 27% of stores and low-fat granola bars in 43%). Overall, 51% of stores had fresh fruit and 49% had fresh vegetables. Few stores carried a range of healthier snack alternatives in single-serving packages. All stores had less healthful impulse purchase items available (e.g., candy) while only 46% carried healthier impulse items (e.g., fruit). Most stores (97%) had food/beverage advertising. Overall, convenience stores located in close proximity to secondary schools represent an important and understudied component of the youth food environment.

Abstract
BACKGROUND This paper describes Project FIT, a collaboration between the public school system, local health systems, physicians, neighborhood associations, businesses, faith-based leaders, community agencies and university researchers to develop a multi-faceted approach to promote physical activity and healthy eating toward the general goal of preventing and reducing childhood obesity among children in Grand Rapids, MI, USA. METHODS/DESIGN There are four overall components to Project FIT: school, community, social marketing, and school staff wellness - all that focus on: 1) increasing access to safe and affordable physical activity and nutrition education opportunities in the schools and surrounding neighborhoods; 2) improving the affordability and availability of nutritious food in the neighborhoods surrounding the schools; 3) improving the knowledge, self-efficacy, attitudes and behaviors regarding nutrition and physical activity among school staff, parents and students; 4) impacting the 'culture' of the schools and neighborhoods to incorporate healthful values; and 5) encouraging dialogue among all community partners to leverage existing programs and introduce new ones. DISCUSSION At baseline, there was generally low physical activity (70% do not meet recommendation of 60 minutes per day), excessive screen time (75% do not meet recommendation of < 2 hours per day), and low intake of vegetables and whole grains and high intake of sugar-sweetened beverages, French fries and chips and desserts as well as a high prevalence of overweight and obesity (48.5% including 6% with severe obesity) among low income, primarily Hispanic and African American 3rd-5th grade children (n = 403).

Abstract
Background Previous studies suggest adults gain extra weight during the holiday season, however, few studies have been done with children during this time. The purpose of this study was to evaluate gains in growth among elementary children, and compare differences by gender and weight status. Methods Children’s (n = 90) height and weight were measured before and after their holiday break. Height, weight and body mass index (BMI) and body mass index-percentiles (BMI-%) were evaluated and compared by groups using repeated measures ANCOVA’s. Results On average, children grew 0.82 cm (0.32 in), and gained 0.56 kg (1.2 lbs) and 0.28 BMI units, however the average BMI-% slightly decreased by 0.4%. Overweight and obese children gained significantly more weight, BMI units and BMI-% units compared with normal weight children. Conclusions This study supports that the holiday period may be an important time to target children, especially those who are already overweight and obese.

Abstract
OBJECTIVE The purpose of this study was to determine the effects of total, chocolate, or sugar candy consumption on intakes of total energy, fat, and added sugars; diet quality; weight/adiposity parameters; and risk factors for cardiovascular disease in children 2-13 years of age (n=7,049) and adolescents 14-18 years (n=4,132) participating in the 1999-2004 National Health and Nutrition Examination Survey. METHODS Twenty-four hour dietary recalls were used to determine intake. Diet quality was determined using the Healthy Eating Index-2005 (HEI-2005). Covariate-adjusted means, standard errors, and prevalence rates were determined for each candy consumption group. Odds ratios were used to determine the likelihood of associations with weight status and diet quality. RESULTS In younger children, total, chocolate, and sugar candy consumption was 11.4 g±1.61, 4.8 g±0.35, and 6.6 g±0.46, respectively. In adolescents, total, chocolate, and sugar candy consumption was 13.0 g±0.87, 7.0 g±0.56, and 5.9 g±0.56, respectively. Total candy consumers had higher intakes of total energy (2248.9 kcals±26.8 vs 1993.1 kcals±15.1, p<0.0001) and added sugars (27.7 g±0.44 vs 23.4 g±0.38, p<0.0001) than non-consumers. Mean HEI-2005 score was not different in total candy and sugar candy consumers as compared to non-consumers, but was significantly lower in chocolate candy consumers (46.7±0.8 vs 48.3±0.4, p=0.0337). Weight, body mass index (BMI), waist circumference, percentiles/z-score for weight-for-age and BMI-for-age were lower for candy consumers as compared to non-consumers. Candy consumers were 22 and 26%, respectively, less likely to be overweight and obese than non-candy consumers. Blood pressure, blood lipid levels, and cardiovascular risk factors were not different between total, chocolate, and sugar candy consumers and non-consumers (except that sugar candy consumers had lower C-reactive protein levels than non-consumers). CONCLUSION This study suggests that candy consumption did not adversely affect health risk markers in children and adolescents.

Abstract
BACKGROUND Low-income, urban African-American youth are at higher risk for obesity and less likely to meet dietary recommendations than white, higher-income youth. Patterns of food purchasing among youth likely contribute to these disparities, but little published information is available. PURPOSE To investigate food purchasing behaviors of low-income, urban African-American youth. METHODS A total of 242 African-American youth, aged 10-14 years, were recruited from 14 recreation centers in low-income, predominantly African-American neighborhoods in Baltimore MD. Youth reported the amount of money typically spent on food, the source of this money, the place of purchase, and frequency of purchase for 29 foods and beverages. Data were collected in 2008-2009 and analyzed in 2009-2010. RESULTS Youth reported spending an average of $3.96 on foods and beverages in a typical day. Corner stores were the most frequently visited food source (youth made purchases at these stores an average of 2.0 times per week). Chips, candy, and soda were the most commonly purchased items, with youth purchasing these an average of 2.5, 1.8, and 1.4 times per week, respectively. Older age was associated with more money spent on food in a typical day (p<0.01). CONCLUSIONS Food purchasing among low-income, urban African-American youth is frequent and substantial. Interventions aimed at preventing and treating obesity in this population should focus on increasing access to healthy foods in their neighborhoods, especially in corner stores.

Abstract
Background Childhood obesity has become an important public health problem in Thailand. This study aimed to determine the relationship between self discipline and obesity in Bangkok school children. Methods A case control study was conducted. 140 cases (obese children) and 140 controls (normal weight children) were randomly chosen from grades 4-6 students in 4 Bangkok public schools. Questionnaire responses regarding general characteristics and child self-discipline were obtained from children and their parents. Results Self discipline in eating habits, money management and time management were reported at significantly lower levels among the obese group (p < 0.05). After controlling all other variables, it was revealed that the ranking of factors associated with obesity by adjusted odds ratio (OR) were low self-discipline in managing expenses (3.1), poor home environment (3.0,), moderate self-discipline in time management (2.9), television viewing time ≥2 hours/day (2.6), an obese father (2.2), and an obese mother (1.9). Conclusions It was recommended that parents and teachers participate in child self-discipline guidance, particularly with regard to eating habits, money management and time management in a supportive environment that both facilitates prevention of obesity and simultaneously develops a child's personal control.

Howard PH, Fitzpatrick M, Fulfrost B. Proximity of food retailers to schools and rates of overweight ninth grade students: an ecological study in California. BMC Public Health 2011; 11:68. [PMID: 21281492 PMCID: PMC3041661 DOI: 10.1186/1471-2458-11-68] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2010] [Accepted: 01/31/2011] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The prevalence of obesity and overweight in youth has increased dramatically since the 1980s, and some researchers hypothesize that increased consumption of low-nutrient, energy-dense foods is a key contributor. The potential importance of food retailers near schools has received increasing attention, but public health research and policy has focused primarily on fast food restaurants. Less is known about the relationship between overweight/obesity and other types of retailers. This study aims to investigate the potential associations between nearby 1) fast food restaurants, 2) convenience stores, and 3) supermarkets, and rates of overweight students in California schools. METHODS We examined the rate of overweight ninth grade students in public schools in 2007 using linear regression. The percentage of overweight students per school was determined by a state required physical fitness test, with three different options for measuring individual body composition. Our key independent variables were the presence of three different types of retailers within 800 m network buffers of the schools. Additional independent variables included school ethnic, gender and socioeconomic composition, as well as urban/non-urban location. We obtained the data from the California Department of Education and ESRI, Inc. RESULTS The presence of a convenience store within a 10-minute walking distance of a school was associated with a higher rate of overweight students than schools without nearby convenience stores, after controlling for all school-level variables in the regression (1.2%, 95% confidence interval 0.03, 2.36). Nearby fast food restaurants and supermarkets, however, were not associated with school rates of overweight students. CONCLUSIONS Public health researchers and policy-makers interested in the food environments outside schools should expand their recent focus on nearby fast food restaurants to include convenience stores, which may also be important sources of low-nutrient, energy-dense foods for students.

Translation and implementation of added sugars consumption recommendations: a conference report from the American Heart Association Added Sugars Conference 2010. Circulation 2010; 122:2470-90. [PMID: 21060079 DOI: 10.1161/cir.0b013e3181ffdcb0] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/16/2022]
Abstract
BACKGROUND A 2-day forum was convened to (1) discuss ways to translate the 2009 American Heart Association added sugars recommendations into actions in areas such as regulation, food labeling, nutrient content claims, and practical application in the American diet; (2) review surveillance methodology and metrics for tracking and understanding the impact of reducing added sugars in the diet; and (3) initiate the development of a framework for future collaboration to help Americans implement science-based guidance relative to added sugars. METHODS AND RESULTS More than 100 multinational participants representing scientists from academia and government and stakeholders engaged in food production, development, and processing, food manufacturing and servicing, food and nutrition policy, and nutrition recommendations for the public attended the conference. Presentations included definitions and examples of added sugars, current US and international added sugars perspectives, added sugars in diets of individuals and in the food supply, food technology behind added sugars, added sugars and health, food manufacturer perspectives, added sugars food-labeling considerations, and examples of positive approaches to improve eating behaviors and the food environment. Facilitated breakout sessions were conducted after the plenary sessions to allow participants to contribute their expertise and thoughts. CONCLUSION The American Heart Association Added Sugars Conference is the first step in an important process that facilitates collaboration across science, public health, and industry to foster innovation, partnerships, policy, and implementation of new products and services for the benefit of the health and well-being of the American public. Science has advanced in the area of added sugars and health, creating mounting pressure to use better methods for translation and dissemination of the science for consumer education and for food companies to respond by producing foods and beverages with fewer added sugars. The new science also reinforces the importance of preventing, rather than simply treating diseases, especially overweight and obesity, diabetes mellitus, high blood pressure, heart disease, and stroke. Reducing added sugars consumption is a good target for addressing obesity, along with other sources of excess calories. However, the potential unintended consequences of substituting added sugars with ingredients that may not reduce calories and of increasing other macronutrients or food groups that may not result in a net health gain must be considered. Although there are many challenges to incorporating added sugars to the food label as was discussed during the conference, disclosure of added sugars content on food and beverage labels is an essential element in consumer education and can provide the information and motivation for making healthier food choices. This conference demonstrated the value of interactive dialogue among multiple sectors and disciplines. More disciplines should be at the table to bring expertise to discuss cross-cutting issues related to public policies and offer diverse insights to finding a solution.

The association between overweight and opportunity structures in the built environment: a multi-level analysis among elementary school youth in the PLAY-ON study. Int J Public Health 2010; 56:237-46. [PMID: 21046190 DOI: 10.1007/s00038-010-0206-8] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2010] [Revised: 09/21/2010] [Accepted: 10/04/2010] [Indexed: 01/19/2023] Open
Abstract
OBJECTIVE To examine school-level opportunity structures of the built environment and student characteristics associated with being overweight. METHODS Multi-level logistic regression analysis were used to examine the school- and student-level characteristics associated with the odds of a student being overweight among grade 5-8 students attending 30 elementary schools in Ontario, Canada, as part of the Play-Ontario (PLAY-ON) study. RESULTS Significant between school random variation in overweight was identified [σ²(μ0)= 0.187 (0.084), P < 0.001]; school-level differences accounted for 5.4% of the variability in the odds of a student being overweight. The more fast-food retailers there were surrounding a school, the more likely a student was to be overweight; students in grade 5 were at increased risk relative to students in grades 6-8. The more grocery stores there were surrounding a school, the more likely a student was to be overweight; students in grade 5 were at increased risk relative to students in grades 6-8. CONCLUSIONS Developing a better understanding of the school- and student-level characteristics associated with overweight among youth is critical for informing intervention programs and policies.

Am J Prev Med 2010; 39:195-202.

Abstract
BACKGROUND Studies of the food environment near schools have focused on fast food. Research is needed that describes patterns of exposure to a broader range of food outlet types and that examines the influence of neighborhood built environments. PURPOSE Using data for New York City, this paper describes the prevalence of five different food outlet types near schools, examines disparities by economic status and race/ethnicity in access to these food outlets, and evaluates the extent to which these disparities are explained by the built environment surrounding the school. METHODS National chain and local fast-food restaurants, pizzerias, small grocery stores ("bodegas"), and convenience stores within 400 m of public schools in New York City were identified by matching 2005 Dun & Bradstreet data to 2006-2007 school locations. Associations of student poverty and race/ethnicity with food outlet density, adjusted for school level, population density, commercial zoning, and public transit access, were evaluated in 2009 using negative binomial regression. RESULTS New York City's public school students have high levels of access to unhealthy food near their schools: 92.9% of students had a bodega within 400 m, and pizzerias (70.6%); convenience stores (48.9%); national chain restaurants (43.2%); and local fast-food restaurants (33.9%) were also prevalent within 400 m. Racial/ethnic minority and low-income students were more likely to attend schools with unhealthy food outlets nearby. Bodegas were the most common source of unhealthy food, with an average of nearly ten bodegas within 400 m, and were more prevalent near schools attended by low-income and racial/ethnic minority students; this was the only association that remained significant after adjustment for school and built-environment characteristics. CONCLUSIONS Nearly all New York City public school students have access to inexpensive, energy-dense foods within a 5-minute walk of school. Low-income and Hispanic students had the highest level of exposure to the food outlets studied here.

Lucan SC, Karpyn A, Sherman S. Storing empty calories and chronic disease risk: snack-food products, nutritive content, and manufacturers in Philadelphia corner stores. J Urban Health 2010; 87:394-409.

Abstract
Corner stores are part of the urban food environment that may contribute to obesity and diet-related diseases, particularly for low-income and minority children. The snack foods available in corner stores may be a particularly important aspect of an urban child's food environment. Unfortunately, there is little data on exactly what snack foods corner stores stock, or where these foods come from. We evaluated snack foods in 17 Philadelphia corner stores, located in three ethnically distinct, low-income school neighborhoods. We recorded the manufacturer, calories, fat, sugar, and sodium for all snack items, excluding candy and prepared foods. We then compared the nutritive content of assessed snack items to established dietary recommendations and a school nutrition standard. In total, stores stocked 452 kinds of snacks, with only 15% of items common between all three neighborhoods. Total and unique snacks and snack food manufacturers varied by neighborhood, but distributions in snack type varied negligibly: overall, there were no fruit snacks, no vegetable snacks, and only 3.6% of all snacks (by liberal definition) were whole grain. The remainder (96.4% of snacks) was highly processed foods. Five of 65 manufacturers supplied 73.4% of all kinds of snack foods. Depending on serving size definition, 80.0-91.5% of snack foods were "unhealthy" (by the school nutrition standard), including seven of 11 wholegrain products. A single snack item could supply 6-14% of a day's recommended calories, fat, sugar, and sodium on average (or 56-169% at the extreme) for a "typical" child. We conclude that corner store snack food inventories are almost entirely unhealthful, and we discuss possible implications and next steps for research and intervention.

School's out: what are urban children doing? The Summer Activity Study of Somerville Youth (SASSY). BMC Pediatr 2010; 10:16. [PMID: 20334661 PMCID: PMC2858132 DOI: 10.1186/1471-2431-10-16] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2009] [Accepted: 03/24/2010] [Indexed: 11/17/2022] Open
Abstract
Background Research indicates that in the United States, children experience healthier BMI and fitness levels during school vs. summer, but research is limited. The primary goal of this pilot study was to assess where children spend their time during the months that school is not in session and to learn about the different types of activities they engage in within different care settings. A secondary goal of this pilot study was to learn what children eat during the summer months. Methods A nine-week summer study of 57 parents of second and third grade students was conducted in an economically, racial/ethnically and linguistically diverse US urban city. Weekly telephone interviews queried time and activities spent on/in 1) the main caregiver's care 2) someone else's care 3) vacation 4) and camp. Activities were categorised as sedentary, light, moderate, or vigorous (0-3 scale). For each child, a mean activity level was calculated and weighted for proportion of time spent in each care situation, yielding a weighted activity index. On the last phone call, parents answered questions about their child's diet over the summer. Two post-study focus groups were conducted to help interpret findings from the weekly activity interviews. Results The mean activity index was 1.05 ± 0.32 and differed between gender (p = 0.07), education (p = 0.08) and primary language spoken in the household (p = 0.01). Children who spent a greater percentage of time in parent care had on average a lower activity index (β = -0.004, p = 0.01) while children who spent a greater percentage of time in camp had a higher activity index (β = 0.004, p = 0.03). When stratified into type of camp, percentage of time spent in active camp was also positively associated with mean activity index (β = 0.005, p =< 0.001). With regards to diet, after adjusting for maternal education, children who attended less than five weeks of camp were four times more likely to eat their meals in front of the TV often/almost all of the time (OR = 4.0, 95%CI 1.0-16.2, p < 0.06). Conclusions Summer activities and some dietary behaviours are influenced by situation of care and socio-demographic characteristics. In particular, children who spend a greater proportion of time in structured environments appear to be more active. We believe that this pilot study is an important first step in our understanding of what children do during the summer months.
